Anker 548 Powerbank Test - Outdoor powerbank with practical features

With the new 548 Powerbank, Anker expands its extensive lineup with a model tailored for outdoor use. Due to the large battery capacity of 192 Wh, the powerbank can also be an alternative to the increasingly popular power stations, as long as you can do without a power outlet. Among other things, it offers four USB outputs with a total output power of up to 87 W, a solar charging port and a retractable LED light. We took a closer look at the Anker 548 powerbank in our test.

Scope of delivery

The Anker 548 powerbank comes in an unobtrusive white cardboard box. On this one can only find the product name, the battery capacity and a reference to the 3-year warranty. The powerbank is well packed and protected by polyethylene foam. Besides it, a 0.60 m USB-C cable and an instruction manual are included.

Design and finish of the Anker 548 Powerbank

The Anker 548 Powerbank is predominantly olive green in color, which also makes it look like an outdoor device. There is also a black carrying strap attached to the top end. The powerbank has a square footprint of 11.6 x 11.6 cm and is 20.7 cm high. With a weight of 2.34 kg, it is by no means light, but can still be transported well.

On the top, the olive green case is interrupted by a ring of transparent milky silicone. The LED illumination, which can be extended by up to two levels, is hidden behind this.

The front features a display, two controls and all of the powerbank’s ports. Among other things, the display shows information about the battery status, the current input and output power, and the remaining charge or runtime. Below the display, there is the LED light button on the left, which also turns on the display, and the SOS button on the right. These two buttons are the only operating elements. Further down are the powerbank’s inputs and outputs, which we will discuss in detail later. The left and right sides of the case also house light strips and vents for air and heat exchange, respectively.

The material quality and workmanship of the Anker 548 powerbank can convince in the test. The superficially slightly rough plastic casing seems rather insensitive and very robust, this also applies to the carrying strap. The workmanship also leaves no room for criticism.

Connection options and compatibility

The Anker 548 powerbank is charged with up to 60 W via the USB-C1 port. This serves as both input and output, there is no separate charging input. Furthermore, the powerbank can also be charged via the XT-60 port with solar modules. These require an output voltage between 10 and 24 V, which means that the currently available Anker solar panels, such as the 625 Solar Panel, are unfortunately not compatible. Alternatively, those who want to charge the powerbank with solar power can use the USB output of the Anker solar panels (the power is significantly lower via USB, however) or use another manufacturer.

In addition to the already mentioned USB-C1 port, another USB-C port and two USB-A ports are available as outputs. The output power is up to 60 W via USB-C1, up to 27 W via USB-C2 and up to 18 W via USB-A. In total, the output power is limited to 87 W, more details can be found in the following overview:

Outputs	Max. output power
USB-C1 + USB-C2	87 W
USB-C1 + USB-A1/A2	78 W
USB-C2 + USB-A1/A2	20 W
USB-A1 + USB-A2	20 W
USB-C1 + USB-A1 + USB-A2	80 W
USB-C2 + USB-A1 + USB-A2	20 W
USB-C1 + USB-C2 + USB-A1/A2	80 W
USB-C1 + USB-C2 + USB-A1 + USB-A2	80 W

Practical test of the Anker 548 powerbank

In testing, we used the Anker 548 Powerbank with a variety of devices, including a Google Pixel 6a, a Lenovo notebook, and various Bluetooth devices. Both the USB-C and USB-A ports were used. The output power always matched that of our other chargers or the maximum charging power of the connected devices. The display confirms this with little deviation. For example, the Google Pixel 6a supports a charging power of 18 W, and the display of the powerbank showed an output of 19 W during charging. The other devices, such as our Lenovo notebook, were also charged without problems. Simultaneous charging of up to four devices also worked smoothly, although the maximum output of up to 87 W quickly limits this. Furthermore, Anker advertises a charge level of 85% after one year of inactivity and up to 3,000 charging cycles. However, we cannot judge both after such a short time.

We used a charger with an output of up to 65 W to charge the Anker 548 Powerbank; no charger is included. The display of the powerbank showed an input of 60 W during charging.

We found the display very convenient in the test, since we can always see the current and exact battery status, the remaining charging time, and the input and output power. On the one hand, this helps to better allocate the battery capacity on the road, e.g. when camping at the weekend or at festivals, and on the other hand, it also helps to recognize problems, such as very slow charging processes of devices. The display turns off a few seconds after a device is plugged in or unplugged.

During longer excursions, the LED illumination also proves to be very useful. It is bright enough to illuminate the surrounding area. Thanks to the extendable design and the two brightness levels, the brightness is also easily adjustable. The powerbank also has an SOS button. If one presses this the LED begins to flash.

Anker 548 Powerbank Test: Conclusion

Anker expands its already large line-up of powerbanks with the 548 Powerbank, an interesting model that is ideal for outdoor use. The powerbank is significantly larger than Anker’s other models, but it is still relatively compact and mobile. It is also well-made and looks very robust. The battery capacity and also the four USB ports are sufficiently sized in our opinion. Furthermore, we like the display, the retractable LED light and also the solar charging port.

However, there are also points of criticism besides the many plus points. The output power can quickly limit multiple devices and could be higher; other power banks offer up to 100 W via a USB-C port and up to 200 W in total. Further, it is a shame that Anker equips the powerbank with a solar charging port and also offers several solar panels themselves, but none of them are compatible.

Overall, the Anker 548 Powerbank is still a very interesting product. However, since it is priced close to smaller powerstations, such as the Anker 521 PowerHouse, at €180 (as of 07/08/2023), prospective buyers should think carefully about which ports and features they need before buying.
